    摘要： Disclosed herein is a vacuum vessel, capable of maintaining the freshness of food contained in the vessel for a lengthy period of time by creating a vacuum in the vessel. The vacuum vessel includes a main body (10) having along an edge thereof an annular protrusion. A seat (15) is disposed in the main body to seat an exterior receptacle containing food therein. A cover (20) covers the main body, and includes a valve mount part and a packing groove defined between inner and outer rings at a position corresponding to the annular protrusion of the main body. A packing (25) is fitted into the packing groove, and has an insert groove to engage with the annular protrusion of the main body, and an extension part to enhance a seal. A check valve (30)(130)(230) is mounted to the valve mount part of the cover.

    摘要： Disclosed is an environment-friendly, pH-neutral, loaded stream extinguishant and a method for preparing the same. The extinguishant is prepared from a mixture of a fire extinguishable component, an organic acid, a surfactant and water. It is very effective in controlling A class fires, as well as showing excellent flame retardance. Also, the extinguishant is neutral in pH so as to neither corrode extinguisher parts, nor affect soil negatively. It can be also applied to portable extinguishers.
